Hi all,
I've been warming up as many of my colleagues to OSM as possible, and
sometimes this comes back to me. Being GIS people, they have GIS
requirements, and OSM was not devised specifically with GIS
requirements in mind. That said, yesterday a colleague approached me
asking why OSM data doesn't comply to the Simple Feature
specification[1] (allowing easy import in for example SQL Server 2008,
which he was actually attempting). The only exceptions apparently
being that self-intersecting polygons are allowed in OSM. He found a
couple hundred in the Netherlands' OSM data.
Is this something that is being considered? I guess it would be easy
to check for self-intersection upon adding / changing a polygon. Is
there a specific reason why self-intersecting geometries would be
explicitly allowed?
Take care,
